Rosie O'Donnell has reportedly admitted that she is "scared" of getting on the bad side of Oprah Winfrey.

The 48-year-old recently secured a deal to host her own chatshow on Winfrey's OWN network to begin in 2011.

"Oprah needed to have Rosie's word before she would move forward," a source told Pop Eater.

"For as big a deal that Oprah is she runs her company like a small business. She wanted to look Rosie in the eye, shake hands and made a deal between the two of them in person."

O'Donnell is also said to be nervous about how a former feud caused during her time guest hosting ABC's The View could affect her perception now.

"The last thing Oprah wants is another Barbara Walters situation on her hands, where Rosie attacks her," another insider said.

"The chances of that happening are zero. Rosie has learned a lot from her experience on The View. She would never put herself in a situation like that again. Plus, to be perfectly honest Rosie is telling friends she's a little scared of her new boss, Oprah."
